Core play meets new chaos

Traditional shot types return – Topspin, Slice and Lob – but the competitive rhythm is remixed by the all‑new Fever Rackets. There are 30 of these rackets, each with a unique effect that can reshape a rally. A Fever Gauge fuels power plays, enabling a Fever Shot that applies your racket’s special twist – and savvy opponents can try to return it to flip the effect back.

• Ice Racket – freezes sections of the court into slippery terrain, changing footing and positioning.
• Mini Mushroom Racket – shrinks the opponent to bite size, affecting reach and coverage.
• Shadow Racket – creates a duplicate of your character, forcing rivals to track overlapping threats.

Modes: from experiments to tournaments

Mario Tennis Fever broadens its format with a mix of challenge ladders, experimental rulesets and broadcast‑style competition. Several options are designed to be approachable for newcomers while offering wrinkles for veterans. Commentary elements and party‑style variants add variety without removing the skill ceiling.

• Trial Towers – climb a series of challenges on your way to the top, testing technique and situational play.
• Mix It Up – unconventional match rules:
  • Ring Shot – thread shots through rings to score points with precision.
  • Forest Court Match – expand the court by feeding Piranha Plants a steady stream of balls.

  Adventure mode: reset the legends

  The single‑player campaign introduces a narrative hook that changes how you rebuild your toolkit. Mysterious monsters transform Mario, Luigi, Princess Peach, Wario and Waluigi into babies, forcing them to re‑master their tennis skills through challenges and encounters. It’s a structured way to learn systems while steadily layering in new techniques.

  Roster and debuts

  The character lineup reaches a series high with 38 playable characters. New arrivals include Goomba, Nabbit, Piranha Plant, Baby Wario and Baby Waluigi. The expanded cast supports varied playstyles, pairing classic shots with Fever Racket strategies.

  Connectivity notes

  Local sharing uses GameShare – a Nintendo Switch 2 system can initiate a session so that up to three nearby players join on Nintendo Switch 2 or Nintendo Switch. Recipients can play the shared software only during that active session. Online features require an internet connection, a Nintendo Account and, in most cases, a Nintendo Switch Online membership; GameChat can be used without a membership until March 31, 2026, after which a membership is required. Some video features need a compatible USB camera, and availability may vary by country.

  Release details and rating

  Release date: Feb. 12. Platform: Nintendo Switch 2 (exclusive). ESRB content descriptor: Mild Fantasy Violence. The overview trailer reinforces the focus on momentum swings – from Fever Shots to environmental court effects – layered atop familiar tennis fundamentals.

  Final takeaway – why it matters

  Mario Tennis Fever leans into high‑variance equipment and playful rule sets while preserving core shot fundamentals, making it approachable yet tactical. If you enjoy arcade‑style sports with system‑driven twists, the Feb. 12 launch sets the stage for both couch sessions and ranked play.

• Ring Shot – thread shots through rings to score points with precision.
• Forest Court Match – expand the court by feeding Piranha Plants a steady stream of balls.
